CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 421,361, dated February 11, 1890.

Application filed September 23, 1889. Serial No. 324,799. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. STEWART, of Kansas City, WVyandotte county, Kansas, have invented certain new and useful Improvements in Gai'GouplingDevices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in car-coupling devices; and it consists in the novel construction and arrangement herein-' after set forth and described.

In the drawings which illustrate the manner of carrying out my invention, Figure 1 is a central vertical section of two drawheads, one showing the link held in position by my improved coup ing-pin, the other with the pin in position for the drop when said couplings shall come together. Fig. 2 is a perspective View of my invention, showing the link and coupling-pin in position. Fig. 3 is a detailin perspective of the pin with my improved abutment rigidly attached thereto.

' Referring to the drawings by letter, A represents my invention; B, the coupling-pin, having rigidly secured to its rear surface a square shoulder or abutment B, for the purpose herein described.

C and O are hearings on which the coupo ling link 19 rests when in position to be coupled to an adjoining car, where the drawheads are at an equal elevation.

D is a square slot in the draw-head immediately behind. and connected with the hole c. Said slot D is made in such a manner as to form a proper receptacle and guide for abutment B.

E is the drawdiead, the shape of which is the same as those now in common use, but embodying my improvements herein described.

a is the lower terminus of the abutment B, this point bearing on the end of couplinglink I), and serves to hold said coupling link b in an almost horizontal position.

d are the rounded shoulders of draw-head E and serve to guide the coupling-link b to the proper point.

e is a notch made in the lower end of the coupling-pin and serves to hold the same in position (illustrated in Fig. 1) before the link is inserted in the draw-head. This, however, I do not claim as being a part of my invention.

The draw-head E has upon its upper surface a casting E, which forms an additional support for the coupling-pin when not in use, as illustrated in Fig. 1.

To use my coupling device where the cars to be coupled are of different heights, I raise or lower the coupling-pin B, thereby 6a bringing the coupling-link b in any desired position. (Illustrated by dotted lines in Fig. 1.)

Heretofore coupling-pins have been made with a head at their upper surface, which serve to hold it in position, but having no effeet on the coupling-pin other than to keep it from dropping from the draw-head. In my improved method of making this pin I utilize the weight of said pin B and abutment B to hold the coupling-link in a horizontal position. I do this by means of bearings O and O, heretofore referred to. When the cars to be coupled are of the same height, the bearings O and O serve to form a rest for-link b, which link is held steady by the weight of pin B and abutment B, as heretofore described. If the cars to be coupled are of different heights, the link is brought in position by raising or lowering the coupling-pin B, thus operating the link Z2, as shown by dot- 8o ted lines, Fig. 1. This improved method of operating said link B will be found much easier and simpler than the old way and obviates the necessity of taking hold of the link with. the hand and holding it in position, 8 5 which in many cases has been the cause of serious accidents. The slot D is made only in the upper portion of the draw-head and of the desired shape and size to receive and hold the abutment B.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a draw head, a casting E, for sup porting the pin when not in use, a circular aperture having in connection therewith a slot for the reception of the e0up1ing-pin,and with a longitudinal lug, substantially as delugs O O, on which-the link is adapted to scribed.

IO rest, substantially as described. In testimony whereof I affix my signature in 2. The combinatiomwith a, draw-head havpresence of two Witnesses. 5 ing a casting E a circular aperture connected WILLIAM H. STEWART;

with a slot for the reception of the coupling- Witnesses: pin, and lugs O O, of a coupling-link held in R. A. BALDERSON, position by a pin B, said pin being formed OLETTA LOWELL.
